10-Foot Python on Loose Has Maine Town Buzzing

The mystery snake has sparked both fear and amusement.

Westbrook, Maine police have released a photograph of a shed snake skin found along a bank of the Presumpscot River, not far from a parkland boat launch site. Residents of the town have been warned to remain at a safe distance from animals while they're spending time along the river and to alert the authorities if they spot the snake.

The enormous stretch of discarded skin is the latest twist in a tale that has social media transfixed by "Wessie," a huge snake that could be a Burmese python or a boa constrictor.

Record 16-Foot Python Bagged in Florida Removal Effort

Westbrook police first spotted in late June what they described as a 10-foot snake eating what they took to be a beaver. That sparked not only an increase in wishful, snake-sighting visitors to nearby Riverbank Park but also more than a bit of concern for the safety of small pets and children.

But, Maine Department of Inland Fisheries and Wildlife biologist Derek Yorks told Bangor Daily News: "It's unlikely that it poses any real danger to people." Yorks estimated that the snake is a Burmese python, which, despite its size will be tough to find, given how well it could camouflage itself. He also noted that the invasive, tropical reptile wouldn't make it through the harsh cold of a Maine winter (the Southeast Asia native species has wreaked havoc in much warmer Florida, however).

As for how such a snake would end up in Maine, it would likely have been raised at first as a pet -- in its early days it's easy to handle but quickly becomes too tough to handle. Within a few years, "it can become burdensome," Yorks said.

Until Wessie is caught either alive or dead and the mystery is finally solved, the snake's burst of fame seems likely to last a little longer. It has its own Twitter handle and local businesses are even capitalizing on the moment, giving the elusive snake its own brand of beer.

VIEW PHOTOS: World's Top Heavyweight Reptiles

This week we learned that back in the last ice age, the first humans to populate Australia likely had to contend with a giant lizard that might have been almost 20 feet long. That got us thinking: Which are the weightiest reptiles among whom modern humans have to live? So here we present the heaviest 10, based on average weight. We'll start small and count up -- getting "fatter," as it were -- until we reach the top heavyweight reptile on Terra Firma. First up, here's the lightest of the top heavies, the false gharial, a freshwater crocodile with a loooong, slender snout. On average, the native Malaysian weighs about 460 pouns (210 kilograms) and runs about 13 feet (4 meters) long.

Careful if you find yourself in a dark alley with this fellow, the mugger crocodile. This 495-pounder (225 kilograms) is an accomplished hunter that hides itself and lies in wait to ambush unsuspecting birds, fish, other reptiles or mammals. It can grow to almost 11 feet long om average (3.3 meters). It's the most widespread of India's three crocodile species.

Heads Up: Crocodiles Climb Trees

Here'a a familiar creature, the American alligator, all 530 pounds (240 kilograms) and 11 feet (3.3 meters) of him.

Alligator mississippiensis, as it's known in the language of taxonomy, is a common inhabitant of coastal wetlands from North Carolina, down to Florida, and across the Gulf of Mexico to Texas.

Remember the false gharial in our first slide? Well, here's a gharial with no false in front of its name. Weighing in at an average 550 pounds (250 kilograms) and stretching nearly 15 feet (4.5 meters) long, it's sometimes known as the fish-eating crocodile. Its name derives from the unique shaping of the end of its snout, which looks like a kind of earthenware pot whose name in Hindi is ghara. The huge hunter is another of India's three crocodile species (like the mugger crocodile we just met).

No slouch in the big reptile department is the American crocodile. We're taking a leap up in size now, as this creature typically runs about 740 pounds, even though it runs a bit shorter in length (13 feet) than, say, the gharial. Though confined largely to southern Florida and Puerto Rico, it still has managed to bounce back as a species. There are a couple of thousand of them now, up from just a couple of hundred in the 1970s. It can eat prey as big as cattle but in general its diet is largely fish-based.

Weighing in at an average 770 pounds or so, the black caiman is One. Enormous. Crocodile. The carnivorous beast lives in the Amazon basin and other freshwater habitats in South America. It can be uncomfortable to think about, but the larger of these crocs can and will eat cute mammals like sloths and monkey. Deer aren't safe either, nor are cattle, horses or dogs.

Did you wonder if we'd ever come to a top heavyweight reptile that wasn't an alligator or crocodile? Here we are! Meet the leatherback sea turtle, the biggest turtle of them all. Unlike other sea turtles, this 800-pound (364 kilogram) creature doesn't have a bony shell. Instead its upside is skin and and flesh. The turtle's range varies widely in the Atlantic and Pacific Oceans. They eat jellyfish, almost exclusively, and are known for migrating many thousands of miles between nesting locations. Lengthwise, they run about the size of an NBA small forward, at 6.6 feet (2 meters).

It's back to crocodiles now, with the orinoco. This monster runs nearly 850 pounds on average, nearly 400 kilograms. The species is listed as critically endangered and exists, in small numbers, only in freshwater habitats of Colombia and Venezuela, especially the Orinoco River. The apex predator will take a shot at anything -- birds, mammals, reptiles. But it mainly eats fish. On land or in water, it stealthily stalks its prey. There are reports it has eaten other, smaller crocodiles like caimans and even consumed members of its own species.

"See you later, alligator! In a ... Nile crocodile???" The Nile crocodile is the second-weightiest reptile in our gallery, tipping the scales at an average of 900 pounds (410 kilograms) and stretching the tape measure to just under 15 feet (4.5 meters). It can be found in aquatic habitats all over Sub-Saharan Africa. The apex predator stalks marshes, lakes, and rivers, eating the usual crocodile diet of mammals, other reptiles, fish, and birds. Their vise-like jaws clamp down so hard that prey just have no chance. They have a structured social order that hands the biggest, oldest males the best places to bask in the sun and first dibs on food.

Finally, we've arrived at the world's biggest extant reptile, the saltwater crocodile (Crocodylus porosus). It weighs on average just under 1,000 pounds and stretches 15 feet long (450 kilograms, 4.5 meters). It can live in saltwater but prefers places like lagoons, deltas, and swamps. They have an incredibly wide range, the widest of any of today's crocodiles -- from northern Australia, thoughout southeast Asia and the east coast of India. And it's our third of India's crocodile species, along with the mugger and the gharial. True to its size, there's almost nothing it won't consider prey. The ambush master will take on mammals, fish, reptile, birds, fish, crustaceans -- you name it. They're thought to have the most powerful bite of any living animal. Steer clear of this one, if you value life and limb.
